[Cbe-oss-dev] Problem with rebuilding latest Linux Kernel for PS3

[John Cunha]

I'm finding it difficult to believe that the Kernelo build is bad or that the install is bad since I have tried building so many kernels and never with any success.
 
I was wondering if anyone out there could give me specific steps to building a kernel ON the PS3 FOR the PS3 that are known to work?
For example:
1- Download kernel 'X' from site 'Y'
2 -Perform step A3 -Perform step B
4 -Perform step C
.
.
8 -Reboot PS3
9 - At kboot execute command 'Z'
I know I'm asking alot but I've been following steps suggested by many web sites on a variety of Kernel sources and never with success.
I would just like to have a starting point for a successful build and reboot that I can work from.
 
Many thanks, again,
John
